Operation Viper

Operation Viper (25-29 July 1950) was the codename given to the attempted South Korean defense of Taejon from the North Koreans. With only ten regiments and without significant support from the United States, the South Koreans suffered heavy losses and were forced to fall back.

Operation
While US Army forces were engaged at the Battle of Kumi to the west, the Korean People's Army threw 28 regiments at the ten regiments that South Korea could muster to the south of Taejon. The South Koreans made a brave stand to the south of the contested town of Taejon, and the United States provided occasional air support to assist their allies, but they were unable to commit any ground troops to Taejon's defense. As a result, Taejon fell to the North Koreans on 29 July, and the South Koreans were forced to withdraw further south.
